Hi,
On Enterprise software it is still possible to add machines to NoMachine Network even if the license has not been activated yet.
Do you receive an error message? Can you go to the Server settings > Security and click Take logs? Please submit these.
Also tell us:
– version of NoMachine software
– which specific product you installed
– did you try a reboot after installation?
– can you tell us if in Settings > Server > Security the server is showing as running?
Activating the license can be done by following the instructions here, skip straight to “How to install the license”: https://kb.nomachine.com/AR10U01206#3
If you have a full Enterprise subscription, please consider opening a support enquiry (you can do this from your User Area) because some of the details that we ask you could mean showing sensitive information. For this reason, your image has been removed from this topic.
